CAR CONSTRUCTION.

Specification of Letters Patent.

Patented May 25, 1909.

Application led Deeember, 1908. Serial N o. 465,912.

To all whom it may concern:

Beit known that I, Jnnonn G. Bowlen, a citizen of the United States, andresident of Chicago, Cook county, Illinois, have invented certain newand useful Improvements in Oar Construction, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, in which like reference characters refer to likeparts, and in which- Figure 1 is a sectional plan view of the undersideof so much of a car body as is necessary to illustrate my invention;Figs. 2 and 3 are detail views of the car body corner cast ings Figs. 4and 5 are like views ofthe door corner castings; Figs. 6 and 7 are likeviews of the center sill and transom brace castings.

An object of the present invention isto reinforce a car body in whichthe bottom of the ear is composed entirely or almost entirely of dropdoors, without interfering with the discharging of the car, the openingor closing of the car doors or car attachments. Y

Wvth this end in View, and referring to the drawings in detail, 1represents the car center sill structure, 2 the car sides, '3 the carend and 4 transoms or cross-'bearers extending between the center sillstructure 1 and the sides 2.

5 are dro doors hinged in any suitable manner to t 1e car underframe,such, for instance, as shown at 6, Fig. 1. On the underside of each ofthe doors 5 I-rivet or secure a diagonal brace member 7 of suitablesection, preferably of Z-seetion. At each end of this member or, atopposite points, on the corners of the door 5I rivet or secure doei'corner braces S which abut preferably the ends of the brace member 7 andare provided with angular projecting engaging faces 8a.

9 are car body corner brace castings provided with angular recessedengaging faces 9*L and riveted or secured to the car body ,in suitablelocation, each opposite a door corner brace casting 8. l() are centersill and transom brace castings having recessed angular engaging faces10 and riveted to the car body each opposite a door corner bracecastmgvS. g he locatlon ofthe several parts as shown 1n Flg. 1 may be'varied by changing the di-` rection of the diagonal 'brace member 7 s0that they run from the central outer end portion of the ca r toward theinterior portion of the car sides, or in a direction at right angles tothe direction shown in Fig. 1, in which event car body brace castings 9would be suitably mounted on or secured to the end central portion ofthe car body, opposite brace castings 8 and likewise with the castings10, which would then be located adjacent the car sides 2 instead of atthe center sills.

As shown in the drawings the castings 9 may be riveted or secured to thebody in such manner that they assist in. tying car side and end sheetingtogether. Likewise the eastings ]0 may be utilized to assist in tyingthe cross-bearers and center sill structure together. Oar body bracecastings 9 are also preferably located just back ofthe pushpole pockets.

In operation, culling strains or shocks, due to the use of a pushpoleagainst pocket 11, will be transmitted through casting 9, casting 8,brace member 7 and opposite casting S, through the casting 10 to thecenter sill sgructure 1. Y

Castings 8, 9 and 10 areso mounted that when the doors are closed a veryslight gap exists between the respective pairs of castings, so that theslight deflection of the parts of the car frame, duc to the bullingstrain, brings the several castings'into engagement to resist saidstrain, or so that an excess of deflection of the car parts andexcessive permanent set is prevented.

Brace members 7 have a further function of stiifening the doors 5 underordinary usage, preventing distortion of the door due to jerking of thedoor-raising chains or mechanism at the time of discharging the.

-desire to secure by Letters Patent.

1. In a car, a door, a brace secured to said door and means on the carproper adapted te contact with said brace to transmit strains theretoand therefrom.

2. ln a car, a door, and a brace for the car proper partly mounted onsaid door.

3. Ina dum car, a drop door and a- Z- section dia ona brace riveted tothe underside Iof'sai door.

'4. In` a car, -a door, a brace extendlng 5 across said door and meanson the car proper in line with and adjacent said brace to transmitstrains thereto and therefrom. 1

5. In a Icar, a door a brace vextendin across said door and enfarged atits ends an 10 means in line with and adjacent the enlarged ends of saidbrace to transmit strains thereto and therefrom. l

6. In a dump car, adrop door, a' brace running across said door incombination with '15 means on the car body to transmit strains to .andmeans in line with and a acent the ends of-,said brace to transmitstrains thereto and therefrom.

9. In a dump car, a drop door, a brace ex- :95 side of said door andhaving enlarged ends 3o tending from one extremity to the other of saiddoon'and having engal g castings at each end-m combmatlon W1t engagingcastings mounted on the car pro er and shaped to receive the castings onsai door to transmit strains through said door.

10. In a dump car, a drop door and a brace extending across saiddoor'andhaving castings at each end with angular projecting engaging faces incombination with engaging castings with recessed en aging facesladjacent and in line with sai door castings to transmit strains throughsaid door castings'.

11.' In a dump car, a drop door, a brace extending diagonally across-said door on its underside, angular castings secured at each end ofsaid brace, an engaging-castin secured to the interior corner of the carbe d the pushpole pocket adjacent and in line with one of the castingson said door and a similar casting secured to the' car cross-bearer andcenter sill structure adjacent the other of` verging toward each otherand the longitudi- I nal center of the car.
